Hi yayapanpan, from the translated text I understood you would like to use Intel® WiDi to connect to your TV. In such case I will move your post to the Intel® WiDi Community.
You would like making sure your TV’s firmware is up to date as well and that your firewall or security software is disabled for troubleshooting purposes.
If issue persists, please provide the Intel® WiDi software version, and msinfo32 report (press Windows* key + R key, type “msinfo32”, press OK and then File, Export) or Intel® System Identification Utility code.
